Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board punching device with adjustable cutting size. Background Technology

[0002] A circuit board, also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. Almost every electronic device, from small items like electronic watches and calculators to large systems like computers, communication devices, and military weapons, uses circuit boards to enable electrical interconnection between integrated circuits and other electronic components. A circuit board consists of an insulating base, connecting wires, and solder pads for mounting and soldering electronic components, serving the dual function of conductive lines and an insulating base.

[0003] Circuit boards typically need to be cut to specified sizes during manufacturing. Common methods include punching. Punching usually requires designing and manufacturing a die of the same size as the circuit board before punching the circuit board substrate. When different sizes of circuit boards need to be manufactured, multiple dies of different sizes also need to be made and replaced. This not only consumes a lot of materials, manpower, and time, resulting in high production costs, but also lacks flexibility and causes inconvenience in production. Utility Model Content

[0006] Furthermore, the cutting edge of the punching die is set at an angle.

[0007] Furthermore, the punching die includes a sliding seat, an adjusting seat, a punching blade, and an adjusting bolt. The sliding seat is fitted onto the adjusting groove, one end of the adjusting seat is axially connected to the bottom of the sliding seat and can rotate up and down, the punching blade is installed at the bottom of the adjusting seat, and the adjusting bolt passes through one side of the sliding seat and limits and fixes one end of the adjusting seat.

[0008] Furthermore, the punching die also includes a synchronizing link, the two ends of which are respectively connected to the sides of the two adjusting seats.

[0009] Furthermore, the supporting component includes a conveyor seat and a support seat, and the processing table is provided with a conveyor chute. The conveyor seat is fitted onto the conveyor chute and can slide left and right along the conveyor chute.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a circuit board punching device 100 with adjustable cutting size, which includes a processing table 10, a mounting frame 20, a support assembly 30, and two sets of punching assemblies 40. The mounting frame 20 and the support frame are both mounted on the processing table 10, and the two sets of punching assemblies 40 are both mounted on the mounting frame 20 and located above the support assembly 30. It is understood that this utility model also includes several driving structures, positioning structures, and automatic control systems, which are all conventional technologies in the field and will not be described in detail here.

[0018] The carrier assembly 30 includes a conveyor seat 31 and a carrier seat 32, and the processing table 10 is provided with a conveyor chute 11. The conveyor seat 31 is fitted onto the conveyor chute 11 and can slide left and right along the conveyor chute 11. The conveyor seat 31 is also provided with a standard slot 311, and the carrier seat 32 is fitted into the standard slot 311. The carrier seat 32 is also provided with a carrier groove 321. The carrier assembly 30, which can slide along the conveyor chute, can be used with a drive structure to automatically convey the circuit board for punching processing, greatly improving cutting efficiency.

[0019] The support assembly 30 also includes a plurality of support blocks 33, which are all fitted into the support grooves 321 and spaced apart from each other. The support blocks 33 can better support the circuit board being cut, while the spacing between the support blocks 33 can provide clearance for the cutting blade, reducing the risk of excessive blade wear or even blade collision.

[0020] The punching assembly 40 includes a punching cylinder 41, a punching seat 42, two sets of punching dies 43, and an adjusting shaft 44. The punching cylinder 41 is mounted on the mounting bracket 20. The punching seat 42 is mounted on the lower end of the punching cylinder 41 and can be moved up and down by the punching cylinder 41. The bottom of the punching seat 42 is also provided with an adjusting groove (not shown). The two sets of punching dies 43 are engaged in the adjusting groove and are arranged parallel to each other. The adjusting shaft 44 passes through the punching seat 42, and its lower end is connected to the gears of the two punching dies 43 respectively. The two sets of punching dies 43 of the punching assembly 40 are arranged perpendicular to each other.

[0021] When cutting a circuit board, firstly, the adjusting shafts 44 of the two sets of punching components 40 are rotated according to the cutting dimensions. The adjusting shafts 44 drive the punching dies 43 to adjust the spacing. Next, the circuit board is placed on the carrier component 30, which transports and positions the circuit board below the first set of punching components 40. Then, the punching cylinder 41 drives the punching dies 43 downward to punch the circuit board, cutting out two parallel edges. Finally, the carrier component 30 continues to position the circuit board below the second set of punching components 40, cutting out the other two parallel edges of the circuit board, thus completing the circuit board cutting process.

[0022] In this embodiment, the cutting edge of the punching die 43 is inclined. More specifically, the punching die 43 includes a sliding seat 431, an adjusting seat 432, a punching blade 433, and an adjusting bolt 434. The sliding seat 431 is engaged with the adjusting groove, one end of the adjusting seat 432 is axially connected to the bottom of the sliding seat 431 and can rotate up and down, the punching blade 433 is mounted on the bottom of the adjusting seat 432, and the adjusting bolt 434 passes through one side of the sliding seat 431 and limits and fixes one end of the adjusting seat 432. The inclined cutting edge allows the punching die 43 to apply more concentrated and precise force to the surface of the circuit board when punching, which can effectively improve problems such as cracks in the circuit board during the punching process. In addition, the adjustable inclination angle of the punching die 43 can also cut the length most suitable for the side length of the circuit board according to the punching depth, reducing the generation of waste debris after cutting.

[0023] The punching die 43 also includes a synchronizing link 435, the two ends of which are respectively connected to the sides of the two adjusting seats 432. The synchronizing link 435 can ensure that the tilt angle of the punching die 43 on the same punching assembly 40 is consistent, avoiding the processing defects of inconsistent punching depth.

[0024] In summary, the beneficial effects of this utility model's circuit board punching device 100 with adjustable cutting size are as follows: by designing a punching component 40 with adjustable spacing between punching dies 43, the circuit board punching device can cut circuit boards of any size and specification without changing the dies, making it flexible and cost-effective; the inclined blade setting of the punching dies 43 can effectively improve the problem of accidental breakage of the circuit board due to impact during the punching process; the design of the automatic feeding support component 30 can greatly improve the cutting efficiency of the circuit board; this utility model is highly practical and has strong promotional significance.

[0025] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
